Jeremy Davies Ruins This (and every) Movie
Jeremy Davies is one of the least talented actors around, and he single-handedly manages to ruin every film (or at least scene) that he appears in.
In every movie, he plays the same twitchy persona with the same halting speech, flapping arms, and zig-zagging fingers. He seems to think that going through these same gestures is a convincing portrayal of insanity. It would be a fine act for a circus freak, but it gets tiresome when dragged from movie to movie. It's especially noticeable when he's cast opposite people like Bale and Zahn who can actually act.
